Abstract
High-speed oxide-confined 980 nm vertical cavity surface emitting lasers (VCSELs), exhibiting very temperature stable static and dynamic characteristics, are presented, which are well-suited for future optical data link and high-performance computing applications. Error-free operation at data rates of 25 Gbit/s in a wide temperature range from 25 to 85 °C is achieved without the need to adjust any of the electrical driving parameters. Small-signal modulation of VCSELs with different oxide aperture diameters is analyzed to identify the primary mechanisms that control device modulation rate by extracting the standard two-pole rate equation parameters.
